This is one of my favorite characters in in the comic Closer. He's an otter named Andy, and is best friends with the main character Jayden.

If you can't tell, the comic is set in the 80s, and will touch on the very earliest appearance of the bottomless district even though most of the pages are set in the main city. Most of the settings revolve around corporate brokering, and for that task the main character has a special way of handling his boss's clients...
